Sounds crazy, I know. But taking note that the first new DPS class was a melee class, Machinist is ranged physical, the trend would dictate that a caster would be the next DPS class introduced sometime later. Why not take the opportunity to mix things up a little and create a unique class in a melee fighter that deals magic damage? Perhaps a "Psychiccer" of sorts, if you will?

I'd envision its skills would perhaps involve direct physical/magic damage, buffs and debuffs, an AoE or two, and some mild support abilities. What do you think?
